Background & objectives: Cell phone microwave (MW) is one of the most harmful physical agents in modern society. This study was designed to determine the effects of exposure to cell phone microwaves on mice sperm morphologic indices. Methods: Animals were divided into two groups including: Microwave (MW) (n=6; exposed to 950-MHz cell phone MW with 5 W output power density and 200 KHz modulatio...

The mechanism by which pertussis toxin induces morphological changes in Chinese hamster ovary cells was studied to determine whether the resulting clustered growth pattern is due to toxin-catalyzed ADP-ribosylation of a cellular substrate. While pertussis toxin was extremely potent in inducing morphological changes in Chinese hamster ovary cells, preparations of isolated A subunit or B oligomer...

Solidification morphology directly impacts the mechanical properties of materials; hence many models of the morphological evolution of dendritic structures have been formulated. However, there is a paucity of validation data for directional solidification models, especially the direct observations of metallic alloys, both for cellular and dendritic structures. In this study, we performed 4D syn...

Microgravity offers excellent advantages for tissue engineering by modulating cellular morphology, metabolism, secretion, proliferation, and stem cell differentiation. In article 2202768 Yannan Zhao, Jianwu Dai co-workers, current simulated-microgravity devices cutting-edge advances of microgravity biomaterials-dependent or biomaterials-independent are summarized discussed to offer a reference ...

Abstract Cell-based high content imaging has become a versatile and powerful method for studying e. g. cellular viability, morphology or physiology. However, its various applications require complex as well expensive hardware consumables, limiting utility usability. To broaden the applicability of cell-based imaging, we have developed tools assaying techniques being exemplary portrayed in this ...

Different blends of a linear polypropylene (L-PP), long-chain branched (LCB-PP), and polyolefin elastomer (POE) are prepared foamed using core-back injection molding. The objective is to analyze the use POE LCB-PP as complementary strategies improve cellular polymers’ impact response. parameters then studied in molded plaques understand samples’ mechanical behavior. Parameters such interfacial ...

Frog ribonucleases have been demonstrated to have anticancer activities. However, whether RC-6 ribonuclease exerts anticancer activity on human embryonal carcinoma cells remains unclear. In the present study, RC-6 induced cytotoxicity in NT2 cells (a human embryonal carcinoma cell line) and our studies showed that RC-6 can exert anticancer effects and induce caspase-9 and -3 activities. Moreove...

micrornas (mirnas) represent a class of small non-coding rna molecules that regulate gene expression at the post-transcriptional level. they play a crucial role in diverse cellular pathways. ionizing radiation (ir) is one of the most important treatment protocols for patients that suffer from cancer and affects directly or indirectly cellular integration. recently it has been discovered that mi...

In response to cellular and environmental stresses, mitochondria undergo morphology transitions regulated by dynamic processes of membrane fusion and fission. These events of mitochondrial dynamics are central regulators of cellular activity, but the mechanisms linking mitochondrial shape to cell function remain unclear. One possibility evaluated in this review is that mitochondrial morphologic...
